16) y varies directly as x is the same thing as y=mx where m is the constant
for the first equation where the length is 7 and weight is 49 there fore
7=m49 in which m=1/7 so to find the length of the 2nd equation
y=m63
y=1/7 x63
y=9 inches
17)The raiser with the $6.25 would raise more money because if 25 ticket is sold and money received is $125 then each ticket is sold for $5 which means if the ticket is sold for $6.25 then 25 would bring in $156.25
Answer:
x=-1 and y=-5
Step-by-step explanation:

Given expressions let them given as two equations
- y=2+7x....... equation (1)
- -2x+6y=-28..... equation (2)
Thus, substitute y=2+7x into equation (2)

simplify it

subtract 12 from both sides

divide both sides by 40

Therefore, as we get the value of x=-1 substitute it to equation (1) and solve for variable y

To be more sure make a cross check on both of the two expressions
Thus,
1) y=2+7x .... substitute y=-5 and x=-1 and check if it is equal
-5=2+7(-1)
-5=2-5
-5=-5
2)-2x+6y=-28... substitute and check
-2(-1)+6(-5)=-28
2-30=-28... (-a)(-b)=ab
-28=-28
Hope it helps!
Answer:
Each person would receive maximum 0.8 pounds of potato.
Step-by-step explanation:
Given:
Total Amount of Potato = 16 pounds.
Number of people attend reunion = 20
We need to find the largest amount of potato each person would receive.
Solution:
largest amount of potato each person would receive can be calculated by dividing Total Amount of Potato with Number of people attend the reunion.
framing in equation form we get;
largest amount of potato each person would receive = 
Hence Each person would receive maximum 0.8 pounds of potato.
Her total distance (so 265 miles) over the number of hours she drives will give miles per hour.
265miles/5hours=53 miles/hour
Been a bit since i’ve done this kind of problem.
X+4=20
X is the number of hours needed to work, while 4 is the hours already there.
